Internet Speed Tests
I have Preferred Internet service (up to 50 Mbps). During a technical chat session about download speed, the Cox support representative ran some tests and recommended I upgrade my cable modem and select a model in the Cox Preferred or Ultimate class. An Arris SBG7580-AC modem and Wi-Fi router was installed on 17 January 2018. After the installation, eight speed tests using the speed test available on your website were run: seven tests reported lower download speeds than what I was receiving with the ‘old’ modem, and only one test indicated an improvement.
Later, a ‘Service Verified’ call was scheduled for 18 January 2018. The technician initiated speed tests using fast.com and speedtest.net that provided significantly different results. Tests from both of these websites reported approximately 50% greater download speeds when compared to the speed test available on your website.
So … why such a discrepancy? Which site is the most accurate?
